ARIA (sometimes mistaken for Orion) Control is the 512th
Test Wing Operations Center, Edwards AFB, California. They
are usually found working ARIA -Advanced (sometimes called
"Airborne", & originally "Apollo") Range Instrumentation
Aircraft (EC-18/EC-135's, 452nd Flight Test Squadron, AF Flight
Test Center, Edwards AFB CA. They were formerly the
4950th Test Wing at Wright-Patterson AFB, OH. Advanced Range
Instrumentation Aircraft do provide flight support to launches
from the Eastern Test Range (aka Cape Canaveral AFS, Fl, aka
Cape Radio) including some shuttle missions. They also support
launches from the Western Test Range at Vandenburg AFB
(call sign ABNORMAL 10). These special aircraft are used worldwide
to track & receive telemetry from rockets, missiles, satellites, etc.
during the times they aren't capable of being tracked by the
traditional ground-tracking network.

...Apollo 11 rushed on through the night, and after a brief glimpse
of the Goldstone station in California where they managed to snatch
a minutes worth of television to the ground, they prepared for firing
the Saturn rocket to kick them onto the track for the moon. Their
orbit had been very accurately measured through the tracking stations,
all checks were completed, and now they were positioned ready to
leave the Earth. Calculations figured a burn of 5 minutes 47 seconds
at 2 hours 44 minutes after liftoff over the Pacific Ocean. In the
darkness below them Boeing 707 Apollo Range Instrumented Aircraft,
ARIA's, were following their track to record every move they made
for transmitting back through tracking stations to Houston later....
